The HP-UX 11i Java Development Kit (JDK) for the Java™ 2 Platform Standard Edition 7 (Java™ SE 7) provides the programming tools and
runtime environment that allow you to deploy version 7.0 technology with the best performance on HP Itanium® 11i v2 (11.23) and 11i v3 (11.31) systems. The JDK includes the HP-UX 11i Java Runtime Environment (JRE). Java 7.0.x has only one download depot file, which contains both the combined JDK/JRE and the stand-alone JRE. During the installation procedure you will be able to choose which one you want to install.

Required Patches

Some HP-UX patches may be required for your Java version. First, we recommend that you have the latest HP-UX Quality Pack installed. To obtain it, go to the HP Support Center site at www.hp.com/go/hpsc (you need an HP-UX support contract to obtain quality packs and patches). Then to see what patches are required for your Java version and HP-UX version/Quality Pack, go to the HP-UX Java Patch Information page, and follow the recommendations for your Java version. The Java Patch Information page also shows you how to determine which Quality Pack is installed on your system. JDK/JRE 7.0.x patch requirements are the same as for 6.0, plus any additional ones listed in the Java 7.0.x Release Notes.

Known Issues:

fileChannel.map is implemented using mmap on the underlying operating system. On HP Integrity Itanium®
servers running HP-UX 11i, multiple mmap calls of overlapping regions of a single file with the MAP_SHARED flag specified
in the mmap call, would result in an error. (See the mmapmanpages for more details.)
To workaround this problem, -Xmpas:on can be used. For an MPAS process, each call to mmap is
independent of other mappings made by the same process.
java -d32 -Xmpas:on <java class>java -d64 -Xmpas:on <java class>
This causes the mpas-enabled Java executable java_q4p to be run, which exists for both 32 and 64 bit. Making the
default Java driver mpas might have a slight negative performance impact.
-Xmpas is available on Java 1.4.2.06 and later.
